Summary
Evidence-based guidelines for anterior cruciate ligament reconstruction rehabilitation emphasize early weight-bearing and supervised exercise for optimal recovery. Personalized rehabilitation plans, lasting at least nine months, are crucial for improved function and reduced re-injury risk.
Area of Science:
- Orthopedics
- Sports Medicine
- Rehabilitation Science
Background:
- Anterior cruciate ligament (ACL) reconstruction is a common surgical procedure.
- Effective rehabilitation is critical for restoring knee function and enabling return to sport.
- Variability in clinical practice necessitates evidence-based recommendations.
Purpose of the Study:
- To establish evidence-based recommendations for individual rehabilitation interventions following ACL reconstruction.
- To provide a consensus framework to guide clinicians and improve patient outcomes.
- To complement existing comprehensive rehabilitation protocols.
Main Methods:
- A modified Delphi process was employed by the German Knee Society.
- 29 rehabilitation topics were evaluated based on systematic reviews and clinical studies (A1-C).
- Expert panel consensus (≥80% agreement) and GRADE framework were used to rate evidence and recommendations.
Main Results:
- Consensus was achieved on 25 topics (86%).
- Key recommendations include early weight-bearing, supervised exercise, neuromuscular and proprioceptive training, and rehabilitation lasting ≥9 months.
- Specific interventions like plyometric exercises, blood flow restriction, core stability, and aquatic therapy show benefits for strength, function, and early return to activity.
Conclusions:
- The consensus provides a multimodal, evidence-based framework for ACL rehabilitation.
- Adherence to these recommendations can reduce clinical practice variability.
- Implementing these guidelines supports safe return to sport and may decrease re-injury rates.
